Add an error message for trying to connect over HTTP with HSTS enabled

Previous error message for this situation:

The previous error message was not related to what I was doing wrong, so it took me a while to realize that the error was coming from the fact that I forgot to use HTTPS.

Just out of curiosity: what is the HTTP response status code you get along with the Null response data? Is it still status 200? The pocketbase documentation does not list a scenario where response data to auth_with_password may be empty.

Possibly this is a bug in pocketbase itself (or the reverse proxy you use) and not an issue for the client.

I'm using a cloudflare tunnel, instead of directly connecting to pocketbase

Given that this PR is not solving an issue with pocketbase itself but rather an cloudflare tunnel error code I close due to inactivity
